The A4S International Case Competition (A4SICC) is an exciting opportunity for students across the globe to help shape a future where sustainable business is business as usual. This is the chance for your ideas to be seen and heard by leaders from some of the world’s largest and most influential companies.
With a different focus every year, the A4SICC attracts a diverse group of business and accounting students – the business leaders of the future – and harnesses their drive and creativity to help today’s business executives solve some of the world’s greatest challenges.
This year, we invite students to work together as action-oriented problem-solvers to focus their skills on the business case for nature.
We encourage teams to register their interest in the competition early, including sharing which company they intend to focus their entry on. This will allow us to approach a selection of companies inviting them to support the competition.
The competition is free to enter.
